WATERVILLE, MAINE, A CORPORATION OF MASSACHU- APPARATUS FOR DISINTEGRATING FIBROUS MATERIAL.

1 To all whom it may concern:

Be it known that I, WILLIAM H. S'ronm,

a citizen of the United States, anda resident of Waterville, of Maine, have invented an Improvement in Apparatus for Disintegrating Fibrous Material, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

My invention relates to an improvement in the process of disintegrating fibrous material used in the manufacture of pulp, the object'being to divide, separate, Or roughen' the fibers without breaking or cutting them, thereby producing a stock that w1ll felt better that the stock from an ordinary heating engine.

I have shown one illustrative embodiment of my invention in the drawings hereto annexed, wherein,-

Figure 1 is a side elevation of an embodiment of my invention showing a stock vat, a stock pump, and targets;

Fig. 2 is a relatively enlarged view 100k? ing in the direction of the arrow in Fig. 1

" much quickened, and

.vat is indlcated at Fig. 3 is a side elevation of the parts" shown in Fig. 2;

Fig. 4 is a relatively enlarged plan view of a section of the face of the target; and

Fig. 5 is a cross section taken on the line 5-.-5 of Fig. 4. I

The type of disintegrating apparatus hereinafter described is the same in broad principle as disclosed in my Patents Nos. 1,099,581; 1,099,579; 1,002,307,91'1d 1,099,578 in so far as a disintegrating surface is employed against which the pulp stock is to be projected. I have found, however, that by arranging two or more targets in different planes in such position that. the pulp stock upon being projected against one target may glance or carom tothe surface of another, the process of disintegration is the final product there of im roved.

Re erring to the drawings, a usual stock 1, a usual pipe leads therefor-m as indicated at 2 feeding into a usual pump 3 which is, in turn, connected by thepipe 4 to a delivery head 5.

Nozzles, or delivery heads, in this art have usually been constructed in the shape of a Specification of Letters laten't.

tapering cone, but I find that advantages arise from constructing my nozzle or delivery head in the general shape of a .T which may be attached to the end of the pipe 4 as shown and which may be provided wlth a slot 6, throughwhich pulp stock may be forced. By

slotted delivery head I am enabled to inthus providing a T headed crease the amount of stock Whichmay be projected against the targets without decreasing the eflicacy of the targets in the distintegration of said stock.

For purposes of illustration I have shown two targets 7 and8 appropriately mounted within the vat l, the-upper target 7 being positioned at an incline in front of the delivery head 5, and the lower target 8 at a different incline in such a position that the projected stock being dashed against the target 7 glances therefrom. and strikes against the target 8, thence falling again into the tank.

For purposes of specific illustration I have shown the surfaces of the targets 7' and 8 as serrated, the angular edges 9 of the ser rations l0 lying preferably directly toward the top of the targets (as best shown in Fig. 4) ,in such a manner that the stock when it is precipitated against the targets must encounter the edges of the serrations rather than the flat sides thereof. I find that this arrangement expedites the disintegration of the pulp stock.

f course it is evident that the targets may be provided with other types of disintegrating surfaces without departing from the spirit of my invention; and thatmore than twoangularly disposed targets may be employed according to the needs of a I claim:

plurality of angularlyarranged targets against which said stock may be forced.

2. In an apparatus for disintegrating fibrous material, a stock vat, a pump and stock-conducting pipe connected therewith, said conducting pipe communicating with an elongated opening for the egress of pumped stock, and a plurality of angularly arranged disintegrating targets positioned within range of said opening whereby said stock may be projected against said targets or one of them.

3. In an apparatus for disintegrating fibrous material, in combination, a source of stock supply, an elongated stock egress opening communicating therewith, angularly arranged targets against which said stock may be projected through said egress opening, and means for so projecting said stock.

4. In apparatus for disintegrating fibrous material, in combination, a source of stock supply, a stock egress opening communicating therewith, angularly disposed targets against one or more of which said stock may be projected through said egress opening, and means for so projecting said stock.

' t 5. In an apparatus for disintegrating fibrous material, in combination, the stock vat 1, the conduit 2, 4, the pump 3 connected therewith, the dellvery elongated aperture 6, and the angularly head 5 having an' disposed targets 7, 8 positioned within range of said aperture.

6. In an apparatus for disintegrating fibrous material, a stock vat, a pump connected therewith, a T shaped slot-aperture delivery head, and a plurality of angularly arranged disintegrating targets positioned within range thereof.

7. In an apparatus for disintegrating fibrous materiaha stock vat, a pump connected therewith, delivery head, and a plurality of angularly arranged disintegrating targets pos tioned within range thereof, said-targets being provided with edged projections thereon so arranged that their edges are presented toward the line of projection of pulp. stock passing through the delivery heads-1T7 lln testimony whereof, l[ have signed my name to this specification, in the presence of two subscribing witnesses,
